[Serious complications following gluteal injection of silicone].

Silicone has a broad range of medical applications and plays an important role, for example, in plastic reconstruction. The use of silicone, however, may result in unpredictable consequences for the patient. These range from swelling and erythema at the site of injection and regional lymphadenopathy to the development of disseminated granulomas distant from the administration site. We report a woman who developed extensive distally-spreading ulcerations in both buttocks several years after gluteal silicone injection. Potential systemic reactions of silicone include intrapulmonary granulomas, embolism and related pneumonitis. Moreover, an association with the development of autoimmune diseases and neoplasias has been discussed. Therapeutic options include surgically removing the silicone and topical or systemic anti-inflammatory drug therapy. However, due to the diffuse dissemination of silicone, the former is often not completely possible and for the latter empirical data are limited and follow-up studies are missing. Liquid silicone is no longer authorized in Europe or in the U.S.A. When silicone implants are used, the decision should be weighed carefully and the patient adequately counseled. In addition, follow-up care on a regular basis is mandatory for both those with implants and those who obtained injections of liquid silicone in the past.
